Hi, I was wondering if you had any update on the availability of RDAP and using it to replace WHOIS? Also, is it possible to get a list of every currently registered domain that Jisc is the registry for? Something akin to ICANN’s CZDS platform (newgtlds.icann.org/en/program-s...)? Many thanks.

As we build our datasets, we plan publish more insights that might be useful. Please reach out if there's any data that you'd find interesting to explore. We're starting off with Entra data, along with Whois, SPF and DMARC but there's plenty of things we haven't considered yet!

That’s great, thanks Emily!

Depending on how you read their latest statement, you could infer partial card data and hashed passwords were taken too. The use and placing of "usable" leaves more open questions.

Thoughts go out to everyone under pressure to bring everything back online safely - always an awful position to be in!

I’m almost the same, I still use music for exercising, find it easier to have as a background distraction, but every other opportunity I used to use to listen to music is now a podcast. Hadn’t really thought about it, wow!
